I've been using a Scala for about a year now. Also have used a Motorola H500. The Scala performs about as well as anything else with the 700p. That is, I still have the occassional drop outs from time to time where I have to go to the handset during a call, and the usual unpairing and paring while not on a call. If I've lost the headset icon, usually by simply hitting the main function button on the Scala it brings it back in.
